Engineer-to-Order (ETO) Project Manufacturing

ECOSIRE builds a proper Frappe app — its own module with versioned DocTypes, hooks.py doc events, and controlled migrations — that stitches these flows into one engineer-to-order backbone on your existing ERPNext site. We add an ETO Project layer that binds a Sales Order to a Project, a progressively-defined BOM/routing tree, and a phase/milestone plan. As engineering releases each phase, planners flesh out the next level of the BOM and operations; server-side validate and on_submit handlers keep the project's committed-cost rollup in sync so budget-versus-actual for material and labor is live, not a month-end exercise. A Change Order DocType captures scope deltas and, through whitelisted methods, re-computes the cost and schedule impact and versions the affected BOM so the original baseline stays intact and auditable. Milestone gates drive procurement and production release: material requests and work orders for a phase are only cut when the milestone is approved, using scheduler events to flag phases at risk and doc events to prevent releasing work against a superseded BOM revision.

Everything is delivered as clean, reviewable source in a git repository, with role profiles and permission rules (Project Manager, Engineer, Planner, Procurement) so each function sees and submits only what it should. Client scripts add the in-form UX — phase pickers, budget gauges, change-order impact previews — while the Frappe REST API and whitelisted methods expose the ETO project state to PLM, CAD, or reporting tools you already run. Because it is a native app and not a fork, it upgrades cleanly with ERPNext and targets both v15 and v16.

Build-to-order means exactly that: this is not an instant download. We start with a scoping call to map your ETO flow, quote a fixed scope, then build against it. Typical delivery is 2-4 weeks from confirmed scope, ending with UAT on a staging site, a rollback plan, install and configuration on your instance, documentation, a training session, and a post-go-live support window. You own the source in your own repo.
